I'm getting a 2001, hopefully 2001.5, S4 in may. i had subs and an amp in my previous car and had planned to transfer these to the audi. unfortunately my car was broken into and everything from my subs and amp to my speakers, headunit, radar detector, and garage opener were stolen [:@]. I was wondering if anyone knew the power ratings on the bose system and if it was worth it to reinvest in new speakers, a headunit, subs/amp or just add subs to the standard bose system. any help with this would be greatly appreciated. thanks.

 

i think the bose sounds nice, my bud just decided to add a sub i think i am gonna do the same.

 

I put a system in my 2001 S4...the bose system is amazing (as far as stock stereos go), however when i put the system in (2 12" kenwoods/ 450 watt amp) it took it to a whole new level.

my advice is to invest in a quality but less powerful system because:

a. you do NOT need a headunit because the s4 come w/ 2 preouts
b. the bose amp works with the stock speaker and adds to the power of the subs

let me know if u goy any questions..hopefully this post helped

 

so flabunt you are saying that if you pull out the s4 deck it has preouts built into it like an aftermarket cd player. if so that is tight. subs will be sooner than i thought.

 

yea cus i used to have an expedition and i bought the system for that car and bought an alpine headunit and when i got the S4 i switched the system into the audi and i noticed that there were enough preouts...also the S4 headunit has more capabilities (access to the 6 disc changer, single cd, etc.) and i think it sounds better

 

yeah i wasnt sure if the stock unit had pre outs, i read somewhere else that it didnt and you had to buy rca converters that reduced sound quality

 

flablunt, do you have any recommendations? i was thinking 2 rockford fosgate 10" subs with 200 RMS power each (P210S4) and an alpine v power class D amp, 400 watts x 1 at 2 ohms (mrp-m450). or if i got a multi channel amp, could i power the speakers and the subs at the same time?

 

well lets put it this way...In the S4 i have the 2 Kenwood 12" subs peaking at 1000 watts a piece (500 RMS) and a mono (single channel) Kenwood 450 watt amp...with the way i set it up i had the "weak" 450 watt amp powering only the subs and the stock bose amp powering the stock bose system..its ******* loud...you dont need to go all out cuz no matter wat u throw in there it will sound 2x as loud as you think it will..

so..i think the 10" fosgates are money (but if ur budget is bigger get some JL's) and for ur amp...if u wanna power ur subs and speakers at the same time get the multi...but i suggest getting a mono to power the subs only.. because the way the bose sound system is set up is with a one channel amplifier that takes frequencies from all channels and puts it into one bass channel (hence its ability to bump) so if u get a mono it will be more efficient

 

My suggestion:

1. Get a phatbox (mp3 player for our cars)
2. Do the mod that messes with the Bose system's hidden settings (sounds MUCH better after)
3. Amp and sub/subs (i have an audiobahn amp and audiobahn sub waitin to go in)
4. If you arent satisfied with the sound of your speakers from the bose system, get MB Quarts.

and if you do get 2 subs (10's or 12's regardless) you will have plenty of thump, so to get some more of the bass to come into the cabin, take out the stock subs on the rear deck (not sure how this sounds, but i've heard good things)

 

Tell mee more about the "phatbox". I run my Ipod through an FM tuner, and it works fine, but doesnt sound as good as it could. If there is another solution, please enlighten me!
